Attic insulation foam comes in an aerosol can and expands as it is applied, filling in gaps, holes, cracks and other areas. It is a premium product that can significantly reduce your energy bills, especially when used in conjunction with air sealing.

There are many different types of spray foam and each has its own unique properties. The best type of foam for your project will depend on where you’re insulating and the desired results. It’s important to read the instructions on the can and follow the product recommendations for the best results.

The Advantages of Spray Foam Insulation for Energy Efficiency | New Generation Spray Foam

When properly installed by a trained technician, spray foam is very effective for new construction and retrofitting existing homes. It can be sprayed in attics, crawl spaces and rim joists. It can also be sprayed onto unfinished walls during renovations or when a home is being re-drywalled.

Professionals will use a specially designed rig that ensures the spray foam is properly mixed and is always the right temperature. They will also follow proper safety guidelines and recommend that homeowners vacate the home during spraying and curing times. This is because spray insulation off-gasses large amounts of volatile organic compounds (VOCs) and should only be installed by trained professionals.

It’s worth noting that modern spray foams are increasingly formulated to be environmentally friendly, with low off-gassing and less VOCs. Some manufacturers, including Demilec, are now offering medium-density closed-cell spray polyurethane insulation with a blowing agent that has a lower Global Warming Potential (GWP) than HFC 245fa, the current standard in most closed-cell spray foams.
